BREECI-I APPLIANCE FOR GUNS.

Specification of Letters Patent.'

Patented Oct. 13, 1908.

To all whom it may concern:

Be it known that we, JOHN F. Mmes and HERMAN G. JAKoBssoN, a citizen of the United States and subject of the King of Sweden, respectively, residents of South Bethlehem, county of Northampton, State of Pennsylvania, have invented certain new and useful Improvements in Breech Appliances for Guns, of which the following is a specification.

Our invention relates to breech loading guns and more especially to that character of breech loading guns in which the breech closing mechanism is supported by a carrier hinged at the breech, and our invention consists of means for supporting such a carrier, and also, it desired, for supporting the ext 'actor mechanism, without the necessity of expensive supports upon the breech of the gun, and whereby to reinforce the latter and Jfacilitate manufacture, as fully set forth hereinafter and as illustrated in the accompanying drawing, in which,

Figure 1 is a rear elevation ot suflicient of the breech of a gun adapted for breech closing mechanism to illustrate our invention, and Fig. 2 is a horizontal Asection at the breech of the gun.

The gun has a breech B, and a carrier C supporting the breech closing mechanism, as shown, a threaded breech block D, which may be provided with any suitable means for turning it.

The breech has a threaded socket for the reception of a bushing, and shown, the latter constitutes practically an annular extension or projection 2 of a breech cap A which is connected immovably with the gun constituting practically a fixed and integral part of the breech and which is provided at one side with lugs or other supports 3 3v for the hinge of the carrier C. As shown, these lugs support the hinge pin E upon or with which the carrier swings. In addition, the breech cap may be provided with another annular extension or projection el. which surrounds and reinforces the rear end of the breech, as shown, and to secure the breech cap to the breech the bushing hub or projection 2 is exteriorly threaded and adapt-ed to correspondin g threads in the socket of the breech, thereby permanently completing the breech of the gun. The bushing 2 is also adapted for the reception of the closing mechanism. For instance, it is provided with the usual mutilated screw threads or collars adapted to those of the rotatable breech block D.

The breech cap may further be utilized to support any suitable extractor mechanism. As shown, there is a lug or lugs 5 for receiving the pin upon which the extractor H swings the latter having projections adapted to those upon the carrier C whereby the extractor is properly operated to throw out the cartridge when the carrier C is swung backward to open the breech.

The bushing 2 sustains the rearward thrust of the breech block 011 the explosion of the charge, while the cap A not only supports the said bushing but also supports the breech closing and opening mechanism, thereby reducing the expense and avoiding the machining which results from forming the support for the breech closing and opening mechanism either upon the breech of the gun or upon attachments bolted thereto. Further, by providing the breech cap A with an enveloping or inclosing flange or projection 4L the breech is reinforced and strengthened while a better support is secured for the attachments of the breech opening and closing mechanism and 'for the extractor mechanism. The cap piece A may also be made the means ot supporting the rear portions of the recoil appliances. For instance, it may be provided with lugs G-G, recessed to receive the recoil cylinder piston rods or otherwise constructed so as to support the rear portions ot the recoil appliances.

XVe do not limit ourselves to the use in all cases of the inclosing projection or flange i, as the breech cap may support the bushing and the opening and closing mechanism without said projection or lange, nor do We limit ourselves to any special method of connecting the cap and its bushing with the gun, but claim- The combination in a gun, of a barrel having a socket at the breech threaded internally, and a cap-piece having supports for In testimony whereof We atx our signathe block carrier, a hub threaded internally tures in presence of two Witnesses.
